Zestino Gredge 07RS Semi Slick Tyre – Size in the listing title. Slick and Semi-Slick tyres need to be warmed up (get to working temperature) before they unleash their full grip potential. So when the tyres are cold, be more careful. Few minutes of driving will heat them up. As a general rule, the higher the tyre air pressure, the longer it takes to heat up. (When tyres are rolling, they are working = heating up). If you need that ultimate grip earlier, then reduce the air pressure!

The soft compound Gredge 07RS is the perfect tyre for drivers who are looking to get the fastest lap times or the best performance from their vehicle whilst out on track. Whilst this tyre is street legal, due to the soft compound we recommend that street driving should be kept to the minimum required to get you to the track so as not to put excessive wear on the tyre. If you would like a tyre which works well both on track and on the road, we recommend trying the medium compound Gredge 07R. APC Next Day – Tracked.
